4. Keri Russell

Over the past 15 years, the always adorable Keri Russell has starred in movies like Waitress and Mission Impossible 3, and also in TV shows like Running Wilde and The Americans. But no matter what character Keri plays, she'll always be Felicity to me. While starring in the WB college drama, a curly-haired Keri Russell forever captured the hearts of every guy who was forced to watch the series with his girlfriend.
